According to Extension Weed Scientist, Dr. Mark Renz, although spring precipitation has alleviated some concern about a continued drought, we can expect some lingering effects in 2013 related to weed management.  Many pastures last summer were overgrazed, and only the weeds remained green until the late rains in September.  The combination of slow regrowth this spring and stress on pasture forages last year will result in significant changes in pasture plant composition in 2013, with the potential for weed species to increase. Mark reviewed several management practices to consider in pastures related to weed management in this week’s issue of WI Crop Manager.
